이 글에서 우리는 메를로-뽕띠(1908-1961)의 철학에 있어서 <존재론적 전 회>를 주도했던 저자의 꼴레주 드 프랑스에서의 자연강의(1956-1960)가 어떤 의미 에서 전통적 주체개념과 관련하여 완전히 새로운 사유의 지평을 열었는지를 밝히 고자 한다. 주지하듯이 주체개념은 메를로-뽕띠의 철학에 있어서 시종일관 사유의 중심에 위치한 문제였다. 따라서 그 개념은 지각에 대한 그의 사유가 전개, 심화되 어감에 따라 가장 큰 의미변형을 겪은 개념들 중의 하나다. 자신의 최초의 철학적 기획이었던 지각 현상학이 점점더 그 분명한...

Effects of maleic anhydride content on mechanical properties of carbon fibers-reinforced maleic anhydride-grafted-polypropylene matrix composites
Hyun-Il Kim, Woong Han, Woong-Ki Choi, Soo-Jin Park, Kay-Hyeok An, Byung-Joo Kim 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 6 39-46 (8 pages)
In this work, the effects of maleic anhydride (MA) content on mechanical properties of chopped carbon fibers (CFs)-reinforced MA-grafted-polypropylene (MAPP) matrix composites. A direct oxyfluorination on CF surfaces was applied to increase the interfacial strength between the CFs and MAPP matrix. The mechanical properties of the CFs/MAPP composites are likely to be different in terms of MA content. Surface characteristics were observed by scanning electron microscope, Fourier transform infrared... -

한국탄소학회 Carbon Letters 2016, Vol.19 1 1-11 (11 pages)
In efforts to characterize and understand the properties and processing of phenylethynyl-terminated imide (LaRC PETI-5, simply referred to as PETI-5) oligomers and polymers as a high-temperature sizing material for carbon fiber-reinforced polymer matrix composites, PETI-5 imidization and thermal curing behaviors have been extensively investigated based on the phenylethynyl end-group reaction. These studies are reviewed here. In addition, the use of PETI-5 to enhance interfacial adhesion between... -
Effects of cross-linking methods for polyethylene-based carbon fibers: review

In recent decades, there has been an increasing interest in the use of carbon fiber reinforced plastic (CFRP) in aerospace, renewable energy and other industries, due to its low weight and relatively good mechanical properties compared with traditional metals. However, due to the high cost of petroleum-based precursors and their associated processing costs, CF remains a specialty product and as such has been limited to use in high-end aerospace, sporting goods, automotive, and specialist... -
Effect of surface treatment of graphene nanoplatelets for improvement of thermal and electrical properties of epoxy composites
Minjae Kim, Yeongseon Kim, Sung Hyeon Baeck and Sang Eun Shim 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.1 5 34-40 (7 pages)
In this study, in order to improve the thermal and electrical properties of epoxy/graphene nanoplatelets (GNPs), surface modifications of GNPs are conducted using silane coupling agents. Three silane coupling agents, i.e. 2-(3,4-epoxycyclohexyl)-ethyltrimethoxysilane (ETMOS), 3-glycidoxypropyltriethoxysilane (GPTS), and 3-glycidoxypropyltrimethoxysilane (GPTMS), were used. Among theses, GPTMS exhibits the best modification performance for fabricating GNP-incorporated epoxy composites. The effect... -

중합을 실시, 개시제에 의한 폴리머구조의 영향을 관찰한 결과, 양쪽 개시제 모두 거의 동일한 연쇄이동에서 나타나는 경향과 비슷한 결과를 얻었다. 그러나 개시제에 의한 폴리머의 구조는 설폰산에스테르계 개시제에서는 거의 100% pendant type 폴리머가 생성되는 반면, 할로겐화알킬계 개시제를 사용한 TAO중합은 pendant type 단위와 main chain type의 단위가 소량 생성됨이 확인되어 이것은 구핵성이 높은 할로겐 음이온에 의한 이중이성화중합이 부분적으로 진행되었음을 확인하였으며, 개시제로 Merrifield수지를 사용한 TAO와의... -

Aripiprazole (ARI) is a commonly prescribed medication used to treat schizophrenia and bipolar disorder. To date, there have been no studies regarding the molecular pathological and immunotoxicological profiling of aripiprazole. Thus, in the present study, we prepared two different formulas of aripiprazole [Free base crystal of aripiprazole (ARPGCB) and cocrystal of aripiprazole (GCB3004)], and explored their effects on the patterns of survival and apoptosis-regulatory proteins under acute...
